So I've figured out you can have different sub-layers in inkscape where each layer has it's own tool definition. That's really cool.
I haven't been able to have different "Orientation Points" for each layer which would allow me to have a different "z" depth. It seems that I can only have one orientation point defined for the whole file which locks me to just that one depth for all layers.
Is it possible to have a different depth for a different layer?
(Thanks so much for this tool by the way)
